A history of psycho-neuro-endocrine immune interactions in rheumatic diseases.

Background All active scientists stand on the shoulders of giants and many other more anonymous scientists, and this is not different in our field of psycho-neuro-endocrine immunology in rheumatic diseases. Too often, the modern world of publishing forgets about the collective enterprise of scientists. Some journals advise the authors to present only literature of the last decade, and it became a natural attitude of many scientists to present only the latest publications. In order to work against this general unempirical behavior, Neuroimmunomodulation devotes the 30-year anniversary issue to the history of medical science in psycho-neuro-endocrine immunology. Summary Keywords were derived from the psycho-neuro-endocrine immunology research field very well known to the authors (R.H.S. collects a list of key words since 1994). We screened PubMed, the Cochran Library of Medicine, Embase, Scopus database, and the ORCiD database to find relevant historical literature. The Snowballing procedure helped to find related work. According to the historical appearance of discoveries in the field, the order of presentation follows the subsequent scheme: 1. The sensory nervous system, 2. The sympathetic nervous system, 3. The vagus nerve, 4. Steroid hormones (glucocorticoids, androgens, progesterone, estrogens, and the vitamin D hormone), 5. Afferent pathways involved in fatigue, anxiety, insomnia, and depression (in-cludes pathophysiology), and 6. Evolutionary medicine and energy regulation - an umbrella theory. Key Messages A brief history on psycho-neuro-endocrine immunology cannot address all relevant aspects of the field. The authors are aware of this shortcoming. The reader must see this review as a viewpoint through the biased eyes of the authors. Nevertheless, the text gives an overview of history in psycho-neuro-endocrine immunology of rheumatic diseases.
